Mooj the magician was a malevolent Munchkin enchanter who once usurped the royal throne of Seebania.
Physically, he was a "bent and hideous" old man, at least at the time of his greatest notability. He dwelled in a hut on top of Moojer Mountain, filled with clocks, while hunting the remaining heir to the Seebanian crown. He was eventually defeated by Princess Ozma, the Wizard of Oz, and King Ree Alla Bad. Ozma considered Mooj potentially so dangerous that she transformed him into a single drop of water in the Nonestic Ocean. (Ojo in Oz)
